EACTIVATING
THE
HEAD
AND
TESTING
THE
NOZZLES
Once the print head has been inserted, the fax machine starts the print
head reactivation and nozzle check procedure. This concludes with:
the printing, on the sheet loaded automatically, of a diagnostic
test sheet containing:
- a
numbered scale
, for checking the flow of ink and the
electrical circuits of the print head nozzles.
- a group of
graphics and text
, so that the printing quality
may be evaluated.
the display shows the message:
CHECK PRINTER, 1=EXIT 0=REPEAT.
Print the test sheet as follows:
Check that the numeric scale
is not broken at any point
and that the
black areas
do not
present any horizontal white lines: only under these
conditions is the print head inserted correctly and is working properly.
1. Enter the value
1
if this is the case. The fax machine automatically
returns to its stand-by mode.
2. If breaks or white lines are found, enter the value
0
. Reactivating
the print head and testing the nozzles is then repeated.
3. If the new print test continues to be unsatisfactory, repeat the
procedure again.
4. If the print test result is satisfactory, press the
key to exit
from the procedure.
The fax machine returns to its stand-by mode.
IMPORTANT
When the print head is about to run out of ink, the display shows:
INK LOW
At the same time the fax machine automatically prints a page to
warn you that the ink is running out and you will have to replace
the print head soon.
When there is no more ink, the display shows:
OUT OF INK
To replace the print head, see the section
